ABSTRACT:
A photographic film cassette, having a spool with a slit therein, in which a film trailer is anchored. Abutting walls are formed on the inside of the slit so as to receive the end of the film trailer, and transmit the rotation of the spool to the roll of film. The film trailer anchored on the spool core is guided by a guide portion on the spool core to be wound smoothly in contact with the surface of the spool core. In a preferred embodiment, the spool consists of two spool pieces. A shaft portion of the external spool piece is inserted in that of the internal spool piece. The film trailer is inserted and anchored between the shaft portions which are fitted together.
